4,5-Tetrahydro-1-(imidazol-4-ylalkyl)-1,4-benzodiazepines were found to be potent inhibitors of farnesyltransferase (FT). A hydrophobic substituent at the 4-position of the benzodiazepine, linked via a hydrogen bond acceptor, was important to enzyme inhibitory activity. An aryl ring at position 7 or a hydrophobic group linked to the 8-position through an amide, carbamate, or urea linkage was also important
发现2,3,4,5-四氢-1-(咪唑-4-基烷基)-1,4-苯并二氮杂卓是法呢基转移酶(FT)的有效抑制剂。通过氢键受体连接的苯二氮杂卓的4位疏水取代基对酶抑制活性很重要。7位的芳基环或通过酰胺,氨基甲酸酯或脲键与8位连接的疏水基团对于有效抑制也很重要。2,3,4,5-四氢-1-(1H-咪唑-4-基甲基)-7-(4-吡啶基)-4- [2-(三氟罗甲氧基)苯甲酰基] -1H-1,4-苯并二氮杂(36)的FT IC(50)值为24 nM,在1.25 microM时产生Ras转化的NIH 3T3细胞85%的表型回复,并且EC(50)为160 nM,用于抑制软琼脂中锚定非依赖性生长H-Ras转化的Rat-1细胞的数量。
